Sprint announced today that the 4G LTE network build is under way in more than 100 additional cities within its existing nationwide 3G footprint. Some of the major metropolitan areas in which Sprint 4G LTE is expected to be available in the coming months are Boston; Charlotte, N.C.; Chicago; Indianapolis; Los Angeles; Memphis, Tenn.; Miami; Nashville, Tenn.; New Orleans; New York; Philadelphia; and Washington, D.C. Here's a list of the new cities that will get 4G LTE on Sprint network:

During the pre-launch phase, customers with capable 4G LTE devices may begin to see 4G LTE coverage in these areas and are welcome to use the network even before it officially launches. Sprint plans to announce commercial availability of 4G LTE in these cities in the coming months, at which point we expect coverage, performance and reliability to get even better. Eventually, the markets will fill in until coverage largely matches the existing nationwide 3G footprint. By the end of 2013, Sprint expects to have completed the nationwide build out of the all new 3G and 4G network.

Sprint's Network Vision project expects to be largely complete with the all-new network by the end of 2013. For the most up-to-date details on Sprint's 4G LTE portfolio and rollout, please visit www.sprint.com/4GLTE
